hey @Brian Richardson the troubleshooting tool returning returning 404 means that your SigNoz cluster is not reachable by the application - and hence you dont see any data in SigNoz
just wanted to check - you have set address as suggseted in this grid right? - https://signoz.io/docs/install/troubleshooting/#signoz-otel-collector-address-grid

10/04/2022, 2:00 AMwell no, that's what I am getting at. I am proxying the request into that port via a reverse proxy

10/04/2022, 2:00 AMI have tested via kubectl port-forward and it works, so sadly it seems that Traefik can't forward either Protobuf or gRPC traffic correctly, over http or https.

10/04/2022, 2:01 AMI don't suppose you would know of a reverse proxy configuration that would work?

@Brian Richardson I worked out nginx config to terminate ssl and do auth before otel-collectors. One difference, I am routing grpc request to relevant namespace based on response from auth. Attaching the nginx config if it helps

grpc_pass <grpc://my-release-signoz-otel-collector.platform.svc.cluster.local:4317>;Ankit Nayan

Or you can use keycloak as mentioned in the blog, though a bit harder to setup https://medium.com/opentelemetry/securing-your-opentelemetry-collector-1a4f9fa5bd6f
